Title: Drive circuit for discharge tube
Inventor: SIMONSEN JAN
IPC: H05B41/234
Filed: 2007-09-06
Abstract: The drive circuit 100 comprises a primary circuit 101 and a secondary circuit 102, both arranged to deliver power to the discharge tube 103. The primary circuit 101 comprises a first power supply 104 and a first controller 108 for controlling the delivery of power from the first power supply 104 to the discharge tube 103. The secondary circuit 102 comprises a power storage arrangement in the form of a capacitor bank 112, a second power supply 111 for charging the power storage arrangement 112, and a second controller 113 for controlling the discharge of the power storage arrangement 112.

IPC: H03B19/12
Filed: 2008-01-28
Abstract: A local oscillator circuit for a signal transmitter or receiver comprises a master oscillator input and signal processing circuitry clocked by the master oscillating signal A that generates a local oscillator signal D. The local oscillator signal has substantially no harmonic content at any integer multiple of the master oscillator signal frequency. The local oscillator frequency can be 2/(2n+1) times the master clock frequency where "n" is an integer such as 1, whereupon the master oscillator frequency is divided by 1.5. The local oscillator signal can have a staircase waveform each cycle of which has 2n+1 steps of equal duration v,w,x and of equal step-amplitude y,z, and clocked by transitions of the master clock A. A feedback loop (fig 6, 86) can be used to indicate and improve nulling of the local oscillator signal content at integer multiples of the master clock. The local oscillator can be used to up-convert and down-convert signals for a radio channel transmitter or receiver.

Title: Controlling a generator in response to a reduction in power grid frequency
Inventor: LARSEN EINAR VAUGHN
IPC: H02P9/04
Filed: 2009-04-01
Abstract: An electrical generating system comprises a prime mover 102, an asynchronous generator 104 and a processor 106 to control the prime mover. The processor receives an indication that the power grid frequency is reduced and reduces the speed of the generator from a first speed to a second speed for a period of time and then increases the speed to third speed at the end of the time period. The reduction of the speed of the asynchronous generator results in a momentary increase in a total power output of the asynchronous generator. The time period may be a function of the power grid frequency and a filter time constant. The second speed may be a function of a filtered power grid frequency subtracted from the power grid frequency and multiplied by a first gain value.

Title: A method of mixed data assisted and non data assisted navigation signal acquisition,tracking and reacquisition
Inventor: WANG CHI-SHIN
IPC: G01S1/00
Filed: 2007-10-10
Abstract: The present invention provides systems and methods for enabling a navigation signal receiver to perform both data assisted and non-data assisted integration to provide better integration during signal acquisition, reacquisition and tracking. In data assisted integration mode, a receiver uses known or predicted data bits to remove the modulated data bits of a received signal prior to integration. In non data assisted integration mode, when the data bits are not known or predictable, the receiver uses an optimal estimation or maximum likelihood algorithm to determine the polarities of the modulated data bits of the received signal. This may be done by determining which of various possible bit pattern yields the maximum integrated power. When the modulated data bits are not known or predictable over a limited range, the receiver carries out data assisted integration over the known or predictable data bits and additional non data assisted integration.

Abstract: 1494318 Cigarette conveying system with buffer storage HAUNI-WERKE KORBER & CO KG 28 Feb 1975 [6 March 1974] 10145/74 Heading B8A Filter cigarettes 2 produced in a machine 3 pass between conveyer belts 4, 6 into a variable capacity magazine 12, between conveyer belts 13, 14 and into a packing machine 19 via a magazine 18, the magazine 12 being controlled by a pivoted feeler 29. The feeler, by an electronic contactor 41, controls the direction 8 in which a belt 11 forming the floor of the magazine 12 is driven by a rotary magnet 26. A rear wall 9 is attached to the belt 11 but an upper wall 24 is stationery. A limit switch 42 is actuated by the wall 9 and a limit switch 43 is operated by a cam 44 attached to the belt 11. The drive for the conveyer belts 13, 14 is controlled by a photo-electric cell 48 associated with the magazine 18 and the upper belt is pivotable as indicated at 46. If the capacity of the packing machine 19 is less than the output of the machine 3, the excess output in a region 22 adjacent the feeler 29 causes the feeler to operate the contactor 41 such that the belt 11 and wall 9 are driven leftwards and the excess cigarettes 2 are accommodated. If the excess persists, the machine 3 is stopped by operation of the switch 42 by the wall 9. Should too few or no cigarettes be fed into the region 22 and magazine 12, the feeler pivots to the left and the contactor 41 causes the belt 11 to move rightwards and the supply to machine 19 is maintained. If the reserve in the magazine 12 is used, the limit switch 43 is operated by the cam 44 of the belt 11 and the machine 19 is stopped. The arrangement of the conveyers 4, 6 and 13, 14 facilitates sampling and inspection of the conveyed articles.
